Data Science

Data science is the discipline of collecting, managing, and analyzing data. As more and more aspects of our lives are made digital, data science will play an essential role in our future. Upon completing an undergraduate data science degree or a data science bootcamp program, you can find positions such as data scientist, machine learning engineer, and data architect.

Civil Engineering

Civil engineering is an engineering discipline involving the development and design of buildings and other infrastructure. You would be involved in the construction and maintenance of roads, bridges, airports, and other types of structures. Other than being a civil engineer, you can pursue jobs like marine engineer and structural engineer.

Mechanical Engineering

Mechanical engineering is another engineering discipline, but it is more involved in machinery and designing mechanical systems. Your work may involve designing, building, and testing machines to ensure that they are functioning and serve their purpose. Some of your career choices are mechanical engineer, automotive engineer, and technician.

Electrical Engineering

Electrical engineering involves electricity and any equipment or device that uses electricity. You would be designing technology that allows people to remain safe from the potential hazard of electricity. Other than an electrical engineer, you can become a computer hardware engineer or a test engineer.

Mathematics Education

Mathematics education is the discipline and practice of teaching mathematics. You can teach at several levels, depending on your expertise. You may also be involved in research. Aside from being a mathematics teacher, you can also become a business advisor or community educator.


Statistics is the discipline of collecting and analyzing data to draw conclusions and solve problems.
